I'm afraid there is a trap in computer games trying to accurately simulate real life. This is simply impossible. The most powerful computer on earth cannot make an accurate weather forecast; real phenomena are too complex to understand let alone simulate, there simply cannot be enough processing power for that. The best computer programs can do is to create simplified models of reality. Of course, as technology progresses, these models are becoming more and more accurate, but a game should 'accept' that it is just a game; although tech improvements are welcome, a game's main purpose lies elsewhere. This is the reason why a classic will always be playable and will be better than many -if not most- of its next gen successors. To put it simply: the race for better graphics will never end.
